I'm changing the fuel filter tomorrow. I don't know if this will solve the problem but I guess I need to change the filter anyway after using the diesel injector cleaner. The funny thing about this issue is that most of the time the car is absolutely fine. If something is damaged it would smoke (white) and stutter and misfire all the time but most of the time it actually drives and feels perfect, then it stutters and then goes away again

Faults with both egr valves and maf sensors can be intermittent, Remmy in broken english is giving you the best advice and that is to have live date read from various electronic components in your car, something that your diagnostic tool is either not capable of doing or you don’t understand the concept or both, chrissyyyw also gave good advice and posted an example video of what to look for then mrsweet1991 gives a diagnosis of the injectors in the example video, reading this thread is like watching a train about to crash, a novice with a £50 quid code scanner wont achieve the same result as an experienced guy with a £2k diagnostic machine, you need experience to interpret what the diagnostic equipment is telling you.

The harsh reality is, it could be a number of things and sometimes, INPA won't help.

They're quite complex diesels, lots of different sensors.

I've had juddering and stuttering before caused by a faulty abs / wheel speed sensor.

If you're not confident using INPA, take it to a specialist.

Hi and thank you. You have hit the nail on the head as I am a total novice when it comes to these things. Ideally one would get a reading of what's wrong and I would take it to have that part repaired/changed. If only it was that simple. From the reading I've done quite a lot of different things could be responsible. I wouldn't quite say heading for a train crash though lol as I am eliminating but haven't ruled out getting it live tested at a service centre. The things I've done like diesel fuel cleaner and changing the glow plugs and controller are helpful or were necessary anyway so nothing lost. There is also time as the school runs have started now as well. I'm getting the fuel filter changed which is necessary also and then will take it to be tested thoroughly, hopefully by a workshop that specialises in bmw cars. Hopedully we'll get there timely

Thanks Chtissyyyw and yes that is true re possible causes. I will take it to a specialist to get checked and hopefully we can get to the bottom of this. It is quite frustrating not to mention costly but these are not brand new cars and faults will come up I guess

Apparently there is a EGR fault recall for my model for the UK. I'll see what the situation is here in Spain

I had the fuel filter changed. It's driving absolutely perfectly though to be fair it did mostly prior. Straight after I drove it to an official BMW service to book an engine diagnosis. At least I've found out there is a difference between car and engine diagnostics, which a lot of workshops I asked don't do (just car). Unfortunately the earliest date they have despite my pleading is the 13th of October I still booked it in though. Estimated cost he said is between 90 and 180 euros. I thought diagnostics is diagnostics but he said something like it depends on how long it takes to find the issue. My spsnish is terrible. Honestly I would pay 180E today to pinpoint exactly what the problem is. I will call around some more to see if there's somewhere I can do a thorough diagnosis much sooner though.

Does anyone know if an engine diagnosis, by BMW no less will definitely reveal any and what issues exactly there are with the engine, or could it still result in a 'it could be this or it could be that' type of situation/

No, not necessarily. It should do, but BMW seem similar to a n other garage/car mechanic, out to make profit first, customer satisfaction is paid lip service to.

Look at how many answers you've had here ... and these people are a damned knowledgable bunch. ;)

Yes sadly that makes sense. Well here's to hoping. The appointment is a month away though. I'm really gonna try get someone quicker, though I would prefer BMW themselves.

Thank you, and thanks to everyone who's contributed also. If only it was A or B or C! 😁

I've made another appointment witth another reputable company that do engine diagnosis as well as repairs, replacement or cleaning of injectors etc. This is for the 24th of September which was the earliest date they confirmed. Still it's progress. I'll still see if there's something sooner

Unfortunately, BMW and a lot of 'specialists' just use some kind of fault reading method, INPA, the name escapes me the one BMW use.

I have / had an early morning rough running issue on my 320d. I took it to a good recommended specialist who said it's not the glow plugs, it's not displaying any errors.

This made me think when the car was mapped, they did something to the fault logging side of the ECU.

I bought a CAN adapter and INPA and with Google translate started working my way through the ECU. It was logging codes. Nothing glow plug or module related. There was a re-occurring rough running fault code.

Digging deeper, I found there to be an issue with injector 2. It's on its way out and cold, it's causing the car to run rough. Colder the weather, rougher the start.

After a minute the INPA values return to normal.

Basically, these things can take time to resolve.

I replaced MAF, MAP, Air temp sensor, CAM position sensor, cleaned inlet manifold, blanked swirl flaps and replaced all boost pipes at 150k.

Don't give up on it though. The M47 is still a good reliable engine that will do the miles if looked after. No chain or DPF issues, they still return good MPG.

i think Bmw are still using ista/D i still use Dis. You can truly diagnose with these programs as opposed to just reading out a fault code. You still need a degree of competance to interpret what the program is telling you. I agree M47 and M57 are very good engines but need to be maintained properly, regular oil changes are not enough, periodic temp checks can prevent a whole chain reaction of problems.

Hi thanks but a quick google shows that's just over 400 kms away from me one way. If I'm honest I'm unlikely to drive down there, whatever the outcome with the car. But thanks again

New update. It's been a week now since I changed the fuel filter. In the 7 days since, I have driven at least 120kms each day for 5 of those days, quite the running. The car has not stuttered, misfired or had any issues (it's never before gone more than 3 days without occuring previously and at it's worst just last week it showed up everyday for the last 3 days before changing the filter).
I have also noticed today that my fuel consumption has improved significantly, by my calculations should give another 120 kms more than previously, which is one day of my daily school run.
Now, I cannot conclude obviously that everything is now fine, but it has given me a bit of confidence to wait until the first of the two appointments I have which is on the 24th of September. I have not done anything since and unless it shows up will wait.
Hopefully though it was just a case of dirty injector and dirty, possibly faulty diesel filter. The glow plugs and controller didn't make much difference but well they're changed nonetheless and running fine, after registering a fault code previously.

So i would say if facing something similar start with the simpler cheaper options to at least rule them out first before moving unto more complicated and expensive things.

If the issue does not show up again I am tninking of still going for my appointment and asking for the injector, egr and maf to be cleaned/serviced as that won't do any harm.

Should I just let things be? What should I look out for and/or have serviced in the engine due to long time usage regardless if anyone can help please. Thank you
